DSLR-style portrait blur, from any phone photo

Portrait-style background blur, in plain English

DSLR portrait lenses produce the characteristic sharp-subject smooth-backdrop look because of optical depth of field — wide-aperture lenses (f/1.4 to f/2.8) physically can only focus on a thin slice of the scene at the focal distance, with everything in front of and behind that slice falling into progressive blur. Phone cameras have small sensors and small aperture stops that physically can't reproduce this effect optically — which is why phones do it computationally instead. iPhone Portrait Mode and Google Pixel Portrait use a depth-aware two-pass technique: first they generate a depth map (via dual cameras, lidar, or single-camera ML inference), then they apply a synthetic blur to pixels at greater computed depth than the focus subject. The output is visually similar to optical DSLR blur for typical portraits, distinguishably worse for complex scenes (translucent objects, fine hair, cluttered backgrounds), but good enough that 'phone portrait mode' has become the default expectation for headshots and personal photos in 2026.

This editor brings the same portrait-blur look to any photo after the fact, whether or not the original was shot in portrait mode and whether or not the camera that took it supports portrait mode at all. It starts by finding your subject — the same accurate cutout that powers our background remover — and then softens everything around it, leaving the subject itself untouched by the blur. The intensity slider takes the backdrop from completely sharp at 0 to fully dissolved at 100, with a live preview at every step. The edge treatment matters as much as the blur itself: a soft falloff where the sharp subject meets the softened background is what stops the result looking pasted-on, which is the giveaway in most fake-portrait-blur attempts. Worth distinguishing from our /blur-background/ tool, which is the 'cut the subject out first, then blur the empty backdrop behind it' workflow; this tool is the 'add portrait-style blur to a photo without removing its background' workflow.

Portrait-style blur for photos you've already taken

Portrait-style background blur is a common need, but phone portrait modes only help with some photos. They usually work only for photos shot in that mode on a supported phone at capture time. They don't help with older photos, imported photos, photos from other cameras, or photos that lost their depth data along the way: messaging apps, reduced-quality transfers and most website uploads strip it. This editor gives you the portrait-blur look for free, with no install, no licence and no depth data needed. It works on photos you've already taken. Upload a photo and the background is removed automatically; then choose the blur option to soften the original background behind your subject. If a plain backdrop suits the picture better, try a solid colour, a gradient or a ready background image instead. Where hair or a shoulder edge looks wrong, fix it by hand with the erase/restore brush; a smaller brush size helps around fine strands. Blur hides a busy background, but it cannot sharpen a subject that was out of focus, so start from your sharpest shot. The download keeps your photo's full resolution and carries no watermark.
